• KYNA is known to be an antagonist of NMDAR and nicotinic acetylcholine ⁇ 7 receptor (hereinafter sometimes to be also indicated as ⁇ 7nAChR). Therefore, KYNA is considered to be mainly involved in the control of presynaptic activity of GABA neuron, glutamic acid neuron via ⁇ 7nAChR in the brain, and control of postsynaptic activity of glutamic acid neuron via NMDAR (see non-patent documents 5, 6 and 7).
